Country Of Origin Labeling Needed on Processed Foods

Today's FDA's announcement makes me wonder about the food and feed meeting this criteria that has already entered the U.S. (and other countries) and is part of the channels of trade, i.e., already on store shelves. How are consumers supposed to know what foods contain raw ingredients from China? Does the FDA or another agency have a list of worldwide manufacturers that use Chinese-made raw ingredients? The FDA or other agencies also need to do some testing of food and feed manufactured in the U.S. as well to determine whether melamine is being used as an additive or a binder.
